This study aims to determine the effect of using student worksheet (LKPD) based on the Problem Based Learning model on the mathematical problem solving abilities of students of class VIII SMP Negeri 2 Pangean. This type of research was a quasi-experimental study with a pretest – posttest control group design. The population was all students of SMP Negeri 2 Pangean Indonesia in the 2019/2020 school year. Sampling method was using random sampling technique. Based on the results of data analysis, the posttest mean score in the experimental class was 85.45 and the average value in the control class was 54.5, meaning that the average value of the experimental class was higher than the control class. The two-mean difference test using the t test was significant (2-tailed) 0.000 <α = 0.05, which means that the posttest score of students 'mathematical problem solving abilities was different from the average posttest score of students' mathematical problem solving abilities. which uses scientific learning. So it can be concluded that there is an effect of the Problem Based Learning model on students' mathematical problem solving abilities.

The low learning outcomes of students are caused by several problems encountered during the learning process, such as IPA learning process still used teacher centered and lecturing methode. The result of student learning competence still low result and the teacher hasn�t yet used learning models can make student will be active. One effort was made to improve students learning competence by applying problem solving learning models. This study aims to determine the effect of the use of problem solving, learning model to the students' learning competence SMP 13 Padang. This study is an experimental research using the design of The Static Group Comparison. The study population is all students of Class VIII SMPN 13 Padang. Sampling using purposive sampling technique. The control class uses the learning model commonly used in the classroom IE discovery learning model and experimental class using a problem solving learning model. The research instrument used is a test of learning result and affective and skill assessment in the form of observation sheet. Data were analyzed using t-test for knowledge, competence because the data were normally distributed and homogeneously. Data were analyzed using up-test for affective and skill competence.Result of hypothesis test in both classes of sample, found that class which uses problem solving, learning model have positive effect of student learning competence of Class VIII 6 SMPN 13 Padang such as knowledge, affective and skill competence

      This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test.      The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.
